Some sketch stuff from my breaks at work :y
Here we have a modified TYPE-SIREN, with shoulder and knee armor removed to balance out the weight of the rifle. The off-hand has been modified to act as a stabilizing clamp, and the camera strip common to most SIREN designs has been heavily modified, along with the visual equipment located in the shoulder/torso area. This model also has a high-end radar and jammer. Next to it is a sketch of this particular unit's pilot.
There's also a maralyn "Whirlwind" drone sketch, an autonomous unit made by the maralyn to fight for them (as they don't actually have the greatest numbers population wise). Armed with a plasma / lightning cannon on its chest, two smaller anti-projectile systems on its shoulders, and some "linear-kinetic" skatter guns on the arms.
Last but not least, a sketch of a stealth unit (uses intense jammers and photo-optic camouflage system) made by Apex Industries. This unit wasn't canon before, but I made it because I liked the idea a lot; it was something a friend's Tempesion OC went up against in his on-going short story starring his Sojourner character, Kohtra: [link]
